Reasons why silicone rubber cables tend to bubble when produced
Silicone rubber cables are very common when they are produced, because the production process of silica rubber cables is more complex and it is easier to bubble than ordinary acorn cables. It is mainly caused by the following reasons:
1, glue material itself problem glue content is high, water volatilization in vulcanization causes foaming.
2, the cable core is damp, causing bubbles when heated.
3, vulcanization temperature caused by too high.
In order to avoid bubbling, we should consider the above aspects to eliminate this kind of problem. The specific operational methods are:
1, in the Silicon rubber rubber rubber mixture when the first choice of low moisture content of the meta rubber material, the filling material should be selected dry, can not choose the filling material has absorbed moisture.
2, to pay attention to the drying of the cable core, the cable is not allowed to use hygroscopic materials to fill the cable core, and should be careful not to let the cable core damp, especially in the southern region in Meiyujijie is prone to this problem.
3, vulcanization temperature can not be high, high will be a few decomposition of vulcanization.
These are the reasons for the Silicon rubber cable bubbles, which need to be highly valued by the production department to reduce or not appear.
